sum [BEARING roe .RAILWAYGARS;

To'allwhomz't may concern: 7 Be it known .that I, JOHN F. OCoNNoR, a citizen of the Unitedv States, residing at Chicago, in the county of Cook and State .of

lllinois', have 1 invented a "certain newand 'useful Improvement in SideBearings for side 'beari'ngsfor railway carsl The ob ect of my invent on. is to provide a simple, efficient andfgravlty centering-side caring I V In the'd'ij'awing. forming a part of this specification, Figure 1 is a longitudinal section through parts of car bolsters with my improved side bearing; mounted in connection therewith. F ig.'2 is a horizontal sectaken on line 2-2 of Fig. 1. F 3 is a vertical sectional view taken on line 33 of Fig. 2. Referring to the drawings, 10 denotes the underside of a body bolster of a railroadcar, 11. the upper portion of an-opposed truck bolster, A a retaining member or housing'of the anti-friction bearing, B the anti-friction element proper and C-C supporting pendulums for the anti-friction element I In the drawing I have shown the hearing as attached to the body bolster, and, as

shown, the retaining member A is of sub- I stantially hollow rectangular form having side walls 1212, endwalls 13 and corner lugs 1 ll l by whichit is riveted or otherwise secured to the body bolster. On its 1nterior the member A is preferably provided with inwardly extending shelves 15-15 so positioned as to securely clamp and hold in place a filler plate 16, the latter preferably carryinga hardened insert 17 upon which the bearing of the anti-friction element directly takes place. 1

The anti-friction element B, as shown, is of rocker type and has upper bearing .sur face 18 and concentric lower bearing surface 19, the latter obviously being adapted to.

bear directly upon the truck bolster, although normally slightly spaced therefrom as is the upper bearing surface 18 normally slightly spaced fromthe plate 17. In each end, the element B is formed with an overhanging fiange indicated at 20, having a Specification of Letters Patent. Application filed June 6, 1919.

curved I'BCGSS'OIIYltS under side, as indicated at 2i, adapted to form a pivotal bearing for the element B on the pendulums G. Thisis-shown most clearly in Figs. 1 and 3. Thependulums C, which are two in numgated lug 24 having a round lower edge, as

indicated.- at 25, the latter having pivotal support at the bottom of a recess 26sformed in the side wall of the retaining member A,

- thesidewalls havingledges or shelves 27, as

indicated in Fig; 3,to sustain the weight (J. Below the points of pivotal support of the pendulums C on the member A, said pendulums areformed with heavy-weighted sections of arcuate form, indicated at 2828. The latter normally have their lower edges disposed slightly above the lower bearing surface 17 of the anti-friction element B.

The operation is as follows: As heretofore element B is normally out of engagement with both the upper and lower bearing surfaces. As the two bolsters approach each other and bring the side bearing into action, it is evident that the antifriction element B will be lifted slightly with respect to its retaining memher A until the upper bearing surface 18 of the'element B engages with the plate 17. Relative rotation between the bolsters will then, of course, cause the element B to roll or rock, one extreme position. being shown by the dotted lines in Fig. 1. As the element B is thus rolled or rocked, it is evident that its bearing recesses 21 at the tops of the pendulums will force the pendulums to tilt or pivot about their hearing edges 25 until the pendulums assume the position indicated bythe dotted lines C, in Fig. 1. To limit the rolling movements of the anti-fricmay be provided with inwardly projecting lugs indicated at 29 at each end thereof to form suit able abutments for the fiat edges 3030 of the element B. After the parts have been moved to the dotted position shown in Fig.

71, and assuming the load removed, the

' then be innnediately transferred to the tops I weight of the anti-friction element B Will of the pendulums C and thereafter there will be combined pivotal movement of the pendulums C about their bear1ngs25 to a verse tlCiLl position and'a slmultaneous swinging of the anti-friction element B about its pivotal bearings on the tops of the' pendulums G; In this Way; allthe parts Will be returnedto central or normal position Without toget out of order.

I claim: I 1; In an anti-friction bearing of the character described, the combination with a hollow, retaining'member, of an anti-friction element mounted Within said -member and havingupper. and lower bearing surfaces pended from'said means above'the pivotal sald means and the retain support between mg'anember;

pivotally supported from said retaining member; 7 i and an ZLIltl-illCtlOIl 4 member pivot-ally suspended from said pendulums i above the points of pivotal supports of the latter, ,saidpantrfriction member extending above the pendulums to engage said bearing surface and below the pendulums to thereby adapt it for engagement with an opposed bearing surface. 1

3. In a side bear ng for rallway cars, the

combination with a hollow retaining member adapted to be secured t'o'the under side of a body bolster, said member, having, an upper bearing surface on the interior thereof; of apair ofpend u'lums pivotally supported on the opposite jinterior' sides of said retaining'member;' and an anti-friction eiementpivotally suspended from the upper ends of said pendulums above the points of' pivotal supports thereof on the retaining member, said'anti-friction element extending I both above'andjbelowthe 'pendulums and thereby adapted to engage the bearing surface of the retaining member and an opposed bearing'surface. I V In Witness that I claim the foregoing I have hereunto subscribed myname this 28th "day of May, 1919. i
